PURPOSE:To obtain a spring force having strong compression stress and improve centering and microphonic by allowing the bulb side and the electrode side to be pressed and contacted each other. CONSTITUTION:An aligner 10 which holds an electrode 2 contacts under pressure with a bulb 1 at a contact point 15 in the bulb contact part 12 and contacts under pressure with the electrode 2 at a contact point 16 in the electrode contact part 13. A spring force durable for strong compression stress can be obtained due to the interaction of two contact points 15 and 16 which are opposite each other. Therefore, the generation of eccentricity when the valve 1 is inserted into the electrode 2 is prevented, and the electrode 2 can be held securely for the valve 1 with the spring force of the aligner 10, even if vertical impact is applied to the electrode center A from outside, so centering and microphonic can be improved. |
